    Sammanfattning : In a small nuclear laboratory of a developing country a low voltage D-T neutron generator can be a very useful scientific apparatus. Such machines have been used successfully for more than 40 years in teaching and scientific research. LÄS MER

  3. 3. Studying neutron-induced fission at IGISOL-4 : From neutron source to yield measurements and model comparisons

    Författare :Andrea Mattera; Stephan Pomp; Mattias Lantz; Andreas Solders; Jonathan Wilson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Fission yields represent the probability of producing a certain nuclide in a fission event, and are important observables for fission research. For applications, accurate knowledge of the yields is fundamental at all stages of the fuel cycle of nuclear reactors, e.g., for reactivity calculations, or to estimate (spent) fuel inventory.

  4. 4. Benchmark of simulation of an ion guide for neutron-induced fission products

    Författare :Zhihao Gao; Andreas Solders; Johan Nyberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fission products; simulation; Geant4; GEF; MCNPX; neutron flux; gamma spectroscopy;

    Sammanfattning : Independent yield distributions of high-energy neutron-induced fission are of importance to achieve a good understanding of fission. Even though the mass and charge yield distributions of thermal neutron-induced fission are well known, there are few experimental data for high-energy neutron-induced fission. LÄS MER

  5. 5. Studies of the nuclear processes of proton capture photon production and spallation neutron emission with advanced experimental techniques

    Författare :Johan Thun; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Kärnfysik; Nuclear physics; Kärnfysik; Applied Nuclear Physics; tillämpad kärnfysik;

    Sammanfattning : A series of nuclear reaction experiments have been performed in the intermediate energy range up to 1.6 GeV using advanced techniques to detect and measure neutral ejectiles resulting mainly from proton bombardment of both light and heavy nuclei. LÄS MER
